September Weather in Portland
Is September Right for You?
Advantages
- Perfect outdoor weather - dry, sunny days reach 27°C (81°F) with low humidity, ideal for hiking and cycling without summer's oppressive heat
- Fall colors peak in mid-to-late September - maple trees in Washington Park and Forest Park display spectacular reds and golds, creating Instagram-worthy backdrops
- Harvest season brings food festivals and farmers markets at their absolute best - Hood River apples, Willamette Valley grapes, and local hops are all at peak freshness
- Shoulder season pricing kicks in after Labor Day - hotel rates drop 20-30% compared to summer, and popular restaurants have easier reservation availability
Considerations
- Unpredictable rain starts mid-month - September averages 10 rainy days with sudden afternoon showers that can derail outdoor plans without proper gear
- Daylight shrinks rapidly from 13 hours early September to 11.5 hours by month's end, limiting evening outdoor activities compared to summer visits
- Wildfire smoke can drift in from Eastern Oregon, creating hazy skies and air quality issues that force indoor activities for 3-5 days during bad years
Best Activities in September
Columbia River Gorge Waterfall Hikes
September offers perfect hiking conditions with cooler temperatures and reduced crowds after summer tourists leave. Multnomah Falls and surrounding trails are at their most photogenic with early fall foliage. Morning hikes avoid afternoon rain showers and offer the best lighting for photography. The 51 mm (2.0 inches) of September rainfall keeps waterfalls flowing strong.
Wine Country Harvest Tours
September is crush season in Willamette Valley - the most exciting time to visit wineries. You'll see actual grape harvesting, crushing, and early fermentation processes. Many wineries offer special harvest experiences and tastings of new vintages. The mild 27°C (81°F) daytime temperatures make outdoor tastings comfortable while crisp mornings preserve grape quality.
Mount Hood Area Apple Picking
Hood River Valley orchards reach peak harvest in September with crisp, fresh apples and stunning mountain views. The weather is ideal - warm enough for comfortable picking at 27°C (81°F) but cool enough that apples are crisp and flavorful. Many farms offer additional activities like cider tastings, farm-to-table lunches, and scenic drives through changing fall foliage.
Portland Food Cart Pod Tours
September brings comfort food season to Portland's famous food cart scene. Cart owners introduce heartier fall menus while outdoor seating remains comfortable during 27°C (81°F) afternoon temperatures. Rain isn't frequent enough to disrupt outdoor dining, and reduced summer tourist crowds mean shorter lines at popular carts. Local ingredients like Hood River apples and fresh mushrooms appear in seasonal specials.
Forest Park Trail Running and Hiking
September offers ideal conditions for exploring America's largest urban forest. Cooler temperatures make the park's 129 km (80 miles) of trails comfortable for longer adventures. Early fall colors begin appearing on deciduous trees while evergreens provide year-round green contrast. Morning fog often creates mystical forest atmospheres perfect for photography.
Brewery Hop on Eastside Bike Tours
September's mild weather and reduced tourist crowds make cycling between Portland's famous breweries ideal. Fresh hop season brings special wet-hop beers only available in September and October. The 70% humidity is comfortable for cycling, and afternoon temperatures around 27°C (81°F) make outdoor brewery patios perfect for lingering over locally-made craft beer.
